Procedure 7-4
Testing STM-1/4/16/64/OC-3/12/48/192 protection
switching with traffic on 12xE3DS3 WP service
interface
Use this procedure to perform the following tests on the 6200 network
element:
• 12xE3DS3 WP service interface test (both at the near and far end).
• protection switching on the E3/DS3 WP ports.
Prerequisites
• Make sure that all the optical connectors are cleaned.
• Make sure that you have adequate number of optical test cords.
• Make sure that you have a variable attenuator.
• Make sure that proper cross-connects are provisioned between the
E3/DS3 ports and optical ports at the far end and the near end network
elements (tributary protection group should be created earlier).
• Make sure you have enough SMB-SMB co-axial cables.
• Select a VC12/VT1.5 path and set the Admin reversion mode as
non-revertive or revertive with max WTR time. WTR time ranges from 1 to
12 minutes.
CAUTION
Risk of damage to circuit packs
Electrostatic discharge can damage electrostatic
sensitive devices. Ensure that you are wearing the
antistatic strap connected to the ESD location on the
6200 network element.
DANGER
Risk of eye injury
Avoid direct exposure to laser beam or fiber. Invisible
light can blind. Keep all unused optical connectors
capped.
